The karst topography is formed by the actions of
Answer:
Ground water
Explanation:
Karst topography is formed when the underground water breaks down the bedrock into soluble rocks. Hence, the bedrock of Karst topography is made of soluble rocks such as limestone. There is no surface water and topsoil in this topography and hence, the water from rains become part of the groundwater.
Karst topography is formed by the actions of water-dissolving soluble rock, such as limestone or dolomite. This creates pathways and caverns, leading to the formation of sinkholes, caves, and underground rivers.
Explanation:Karst topography is formed by the actions of water dissolving soluble rock such as limestone or dolomite. As water percolates through the ground, it chemically reacts with the rock, creating pathways and caverns. Over time, these pathways and caverns grow larger, leading to the formation of sinkholes, caves, and underground rivers.
This process is known as karstification. Some examples of karst landscapes include the caves in Kentucky's Mammoth Cave National Park and the limestone hills in the Yucatan Peninsula of Mexico. The type of rocks that once existed in these locations are limestone and dolomite whereas the pH of the nearby groundwater is slightly acidic which is responsible for the formation of caves

The thrifty gene theory suggests that some people have a gene (or genes) that causes them to be _________
The thrifty gene theory suggests that some people have a gene (or genes) that causes them to be more efficient at storing energy as fat.
This genetic predisposition is believed to have evolved in response to periods of food scarcity and famine faced by our ancestors.
Individuals with this gene were better able to survive and reproduce during times of limited food availability by storing excess energy as fat.
However, in modern societies with easy access to calorie-rich foods, this genetic advantage has become a risk factor for obesity and related health issues.
The thrifty gene theory offers insights into the complex interplay between genetics, environment, and the current obesity epidemic.

"what cell gives rise to all formed elements?"
Hematopoietic stem cells in the bone marrow give rise to all formed elements, including red and white blood cells and platelets. This happens through a process called hematopoiesis, during which these stem cells differentiate into different cell types.
Explanation:The cell that gives rise to all formed elements is the hematopoietic stem cell. Found in the bone marrow, these cells are responsible for the production of all blood cells: red blood cells, white blood cells, and platelets. Through a process called hematopoiesis, these stem cells differentiate into various types of blood cells. For example, they can turn into myeloid progenitor cells that eventually become red blood cells, platelets, or certain types of white blood cells. Alternatively, they can become lymphoid progenitor cells, which lead to different types of white blood cells.

In the spinal cord, the small gaps in the myelin sheath between adjacent glial cells are called
The small gaps in the myelin sheath in the spinal cord are termed as Nodes of Ranvier. They are crucial for the speed of signal transmissions, allowing signals to hop from node to node.
Explanation:In the spinal cord, the small gaps existing in the myelin sheath among adjacent glial cells are termed as Nodes of Ranvier. These nodes have a vital role in promoting the speed of signal transmissions by enabling signals to hop from one node to the next rather than traversing the whole length of the axon, a process known as saltatory conduction. Therefore, the Nodes of Ranvier facilitate rapid and efficient neuronal communication. For instance, in a typical neuron, an action potential leaps across many nodes from the cell body towards the axon terminal, effectively speeding up the signal’s journey along the axon.

How does a scientific explanation differ from a nonscientific explanation?
Final answer:
Scientific explanations are based on empirical evidence, are testable and refutable, and can form falsifiable theories. Nonscientific explanations often rely on beliefs or untestable claims, such as supernatural elements. The scientific method requires hypotheses to be tested and potentially transformed into solid scientific theories.
Explanation:
A scientific explanation differs from a nonscientific explanation in several key ways. Scientific explanations must be based on empirical evidence, they must be testable and refutable through scientific investigation, and they generally follow a logical structure that can produce precise and consistent predictions. In contrast, nonscientific explanations may rely on personal beliefs, untestable claims, or supernatural elements that cannot be empirically examined or are not subject to falsification.
For instance, the scientific method requires forming hypotheses that explain observed phenomena logically and consistently. A hypothesis is a proposed explanation for an observation, which can be tested through experimentation and additional research. Over time, repeatedly tested and confirmed hypotheses may develop into scientific theories, which represent the most robust form of scientific knowledge, such as the germ theory of disease. These theories must still be falsifiable to remain scientifically valid.
In comparison, explanations that invoke supernatural causes or are based on anecdotal evidence can't be tested using scientific methods. For example, when examining a phenomenon like broken bones in an ancient population, a scientist would consider natural explanations such as diet or lifestyle, rather than supernatural causes, because these can be tested and have the potential to be refuted.

Which structure of the inner ear is responsible for hearing and which structure is for balance?
Both hearing and balance are functions of the inner ear, but different inner ear structures have unique roles in each.
The cochlea is the part of the body that is primarily in charge of hearing. The cochlea is a spiral-shaped, fluid-filled organ with hair cells, which are specialized sensory cells. When sound waves enter the inner ear, they force the cochlea's fluid to shift, stimulating the hair cells. These hair cells transform the sound waves' mechanical energy into electrical signals, which are ultimately sent to the brain via the auditory nerve. The brain perceives these signals as sound after processing them.
The vestibular system, which is made up of a number of related parts inside the inner ear, is the structure in charge of balance, on the other hand. It has three semicircular canals as well as the vestibule. The utricle and saccule, two tiny sacs found in the vestibule, are in charge of sensing changes in linear acceleration and head position with regard to gravity. In order to detect rotational motions of the head in various planes, the three semicircular canals are positioned perpendicular to one another. These motions are picked up by the vestibular system, which then transmits signals to the brain that aid in maintaining balance, coordinating eye movements, and enhancing spatial orientation.
Hence, hearing is controlled by the cochlea, whereas the vestibular system, which includes the vestibule and semicircular canals, controls balance.

The major metabolic hormones in the body are thyroxine (T4) and triiodothyronine (T3), produced by the thyroid gland. They regulate the body's basal metabolic rate, impacting energy and heat production. Other significant metabolic hormones include catabolic and anabolic hormones that regulate the breakdown and synthesis of molecules, respectively.
Explanation:The body's major metabolic hormone is mostly referred to as the thyroid hormones, specifically, thyroxine (T4) and triiodothyronine (T3). These hormones are produced by the thyroid gland and significantly influence the body's basal metabolic rate - the amount of energy used by the body at rest. They do this by entering target cells and binding to intracellular receptors located on the mitochondria, triggering an increase in nutrient breakdown and oxygen consumption to produce ATP. Moreover, T3 and T4 initiate the transcription of genes involved in glucose oxidation, promoting energy production and heat generation, a phenomenon known as the hormone's calorigenic effect.
It's also worth mentioning other hormones like catabolic and anabolic hormones that play key roles in regulating metabolic processes in the body. Catabolic hormones like cortisol, glucagon, adrenaline/epinephrine, and cytokines stimulate the breakdown of molecules, resulting in energy production, while anabolic hormones such as growth hormone, insulin-like growth factor, insulin, testosterone, and estrogen are required for the synthesis of molecules.

In a bacterium, we will find dna in _____.
In a bacterium, DNA is found in the nucleoid. The nucleoid is a region within the bacterial cell where the genetic material, which is a single circular chromosome, is localized.
Unlike eukaryotic cells, bacteria lack a true nucleus, so the DNA in a bacterium is not enclosed within a membrane-bound organelle. Instead, it is loosely organized in the nucleoid region, located in the cytoplasm of the bacterial cell. The nucleoid contains not only the main chromosomal DNA but also various proteins that help in the organization and regulation of genetic material.
In addition to the nucleoid, bacteria may also contain smaller, circular pieces of DNA called plasmids. Plasmids are separate from the main chromosome and can carry genes that provide the bacterium with additional functionalities, such as antibiotic resistance or the ability to produce certain toxins.
